I'm in awe at the sight of your bare bone shop. It must be the open air atmosphere unrestricting, relaxed settings that such Taj Mahal quality work can be produced from.In this case it's not the tool that makes the job but knowledge! They say a man's only as good as his tools.From what i remember ,you use a dremil mostly?An airbrush and food colorings, or acrylics.I'm shaking my head this very minute looking at all i have ,which is over kill and i'm producing mud pies with state of the art equipment.I guess less is more in your case ,Use what you got,Wow.Boy had you been my teacher i'd have been somebody by now .Thinking about your shop again typing this I'm still shaking my head, You are truly gifted from the one up above .
